iMPRQl/EMENT IN STEAM WATER-ELEVATORS..

Specification forming part of Letters Patent No. 133,747,6ated December 10, 1872; antedated December 4,

'Be it known that 1, WILLIAM BURDON, of Brooklyn, in the county of Kings and State of New York, have invented a new and useful Improvement in Apparatus for Raising and Forcing Water by the Condensation and Pressure of Steam; and I hereby declare that the following is a full, clear, and exact description' thereof, reference being had to the accompanying drawing forming a part of this specification.

Thisinvention relates to that class of apparatus for raising and forcing water, in which a vacuum is alternately formed in two adjacent chambersby the condensation of steam, and water raised in them by atmospheric pressure is afterward expelled by the pressure of steam, which is subsequently condensed to form vacuums for the repetition of the operation. The improvement consists in the p combination with such apparatus, of a rocking-beam arranged in the valve-chest, and having valves formed on its ends and floats attached to said valves whereby, on the lowering of the water in one chamber and rising of that in the other chamber, the shifting of the valve to admit'steam to the latter and shut it off from the former is effected, and vice versa.

'In the accompany drawing, Figure 1 is a central vertical section of an apparatus constructed according to my invention, and Fig.- 2 is a like view of the apparatus in a slightly modified form.

Similar letters of reference indicate corresponding parts in both figures.

Referring to Fig. 1, A A are the main chambers of the apparatus. They may be arranged side by side, as represented, or in any other Both communicate, with a suction-pipe, B, through valves G O, and with a discharge'pipe, D, through outlets E E furnished with valves, not visible in the drawing. The upper portion of this discharge D communicates with the chambers through pipes F F, leading one to each chamber, provided with check-valves a a, capable of opening only toward the chambers. G is a valve-box,-which-is of cylindrical form, and has its ends closed by removable plugs c c. The valve-box issupplied with steam by a v pipe, H, leading from a steam-generator. The

valves dd are formed on the ends of a rock ing-beam, I, pivoted 'in the middle of the valve-box, and they close and open ports 6 0, consisting of short tubes or pipes leading from the chambers to the valve-box, and projecting into the latter some distance. The valves have attached to them, by long rods 1' r, floats J J, which are situated in the lower parts'of the main chamber, and have formed on their sides open-topped water-receptacles b b.

To start the apparatus, its main chambers A A are first filled with water by any convenient means, and the valves are then shifted to admit steam to one chamber, which I will suppose to be the right. The water in this chamber is expelled by the steam admitted to it, and when its level gets below the float J in that chamber, said float lowers with the receding Water, and its weight, combined withthat of the water in its water-receptacle, draws down the valve on the right -hand end of the beam I, and at the same time the float on its left end by its buoyancy, pushes up the left end of the beam, and the right-hand valve 0 is thereby closed and the left opened, and the supply of steam is shut off from the right chamber and admitted to the left. On a slight reduction of pressure in this right chamber the checkvalve in the pipe]? leading to it opens, and a stream of waterissues from-the pipe and condenses the steam in the chamber and forms a vacuum, causing it to fill again by atmospheric pressure. Acting on the water in this chamber the steam expels'it, and when the level reaches the float J the latter lowers with it, and at the same time the float in the right chamber, which is by this time about full, rises by its buoyancy, and the two together shift the beam and close theleft valve and open the right, thereby shutting off the supply of steam from the left chamber and ad- 2 mitting it to the right, which is thereby again discharged. A slight reduction of pressure takes place in the left chamber almost imme.

diately after the supply is shut 0E, and the check-valve of the pipe F leading to the left chamber opens and permits the escape of Water into the chamber from the discharge-pipe, and the steam is thereby condensed and a vacuum formed, into which Water flows by atmospheric pressure. The, apparatus continues to operate in this manner, each chamber filling and discharging while the other discharges and fills.

The apparatus illustrated in Fig. 2 is substantially the same as the one described; but instead of having its floats J J arranged near the bottom of its chambers it has them arranged in their upper portion. In consequence of this the operation is reversed, the shifting of the valves to admit steam to the filled pose set forth.
